Question

What is the speed of a wave that has a frequency of 125 Hz and a wavelength of 1.25 meters? Express your answer to the nearest whole number. 156.25 meters per second

Answer 1

Answer:

The speed of the wave is 156.25 meter per second .

Explanation:

Use the formula for the relation between the speed of a wave and frequency.

$v=f \lambda$

Where f is frequency and $\lambda$ is wavelength .

f = 125 hz

$\lambda=1.25\ meters$

Putting all the values in the formula

$v=125\times 1.25$

$v=156.25\ meter\ per second$

Therefore the speed of the wave is 156.25 meter per second .

Answer 2

156 is the answer. so 156.25 is almost the same thing, you just round. It's not hard. Thank you!!!
